br>So CV/ gate to midi can be real fun, but is there anything that does CV to DMX? I wonder because I often have to do light at work and it's just uninteresting to me. And then I started thinking it might just be fun.... br> br>

just ordered the midi to dmx recently... probably it's technically possible with CV to midi and then Midi to DMX... br> br>

br>Hmmm, CV To MIDI to DMX. I guess I had somewhat of an impopular idea here. Also, I reckon it would be very difficult to get a nice enough amount of CV inputs. 1 CV is only good enough for 1 lamp. Then we have different colours (LEDpar), different movements for moving heads, intensity and frequency of stroboscopes etcetera...

I guess I just had a bad idea. Thanks for the input, though... br> br>

br>Hi,

Just do a search for "analog to dmx" on google. There are lots out there!
Most analogue lighting control systems use a 0 to +10V control with a few being negative.
There are cards from a few channels up to much larger ones of 48 plus.
I worked in the lighting industry for 25 years or so and we had some handy 96 channel ones made by ETC/ARRI called Connexion Plus, probably crop up second hand sometimes.
These ones are available as a pcb:

Not too expensive for a project perhaps, though most moving heads nead quite a few channels, even a MAC500 needs 12 channels in nasty mode 1 so you would need a lot of sources to make a lightshow do anything much!

I wondered about using a memory console with an analogue output to store CV presets at one time, but the resolution of DMX is only 8 Bit and even then, some desks drop a bit in record and only do 8 bits on fades...
